PIN 3. ALARM INPUT 1 (INPUT)
To connect wire from
ALARM INPUT 1 ( PIN 3 )
to
GND ( PIN 9 )
connector, DQR will
start recording and buzzer will be on. When alarm has been triggered, signal becomes
“Low”, and it will stop all alarm activities. Under normal operation, signal remains
“High”.
PIN 4. ALARM INPUT 2 (INPUT)
To connect wire from
ALARM INPUT 2 ( PIN 4 )
to
GND ( PIN 9 )
connector, DQR will
start recording and buzzer will be on. When alarm has been triggered, signal becomes
“Low”, and it will stop all alarm activities. Under normal operation, signal remains
“High”.
PIN 5. ALARM INPUT 3 (INPUT)
To connect wire from
ALARM INPUT 3 ( PIN 5 )
to
GND ( PIN 9 )
connector, DQR will
start recording and buzzer will be on. When alarm has been triggered, signal becomes
“Low”, and it will stop all alarm activities. Under normal operation, signal remains
“High”.
PIN 6. ALARM INPUT 4 (INPUT)
To connect wire from
ALARM INPUT 4 ( PIN 6 )
to
GND ( PIN 9 )
connector, DQR will
start recording and buzzer will be on. When alarm has been triggered, signal becomes
“Low”, and it will stop all alarm activities. Under normal operation, signal remains
“High”.
PIN 7. EXTERNAL ALARM NC
Under normal operation COM connect with NC and disconnect with NO. But when
alarm triggered, COM disconnect with NC, and connect with NO.
PIN 8. EXTERNAL ALARM NO
Under normal operation COM connect with NC and disconnect with NO. But when
Alarm triggered, COM disconnect with NC, and connect with NO.
PIN 9. GND
GROUND
PIN 10. RS485-B
DQR can be controlled remotely by an external device or control system, such as a control
keyboard, using RS485 serial communications signals.
PIN 11. RS485-A
DQR can be controlled remotely by an external device or control system, such as a
control keyboard, using RS485 serial communications signals.
